🛠️ Tool: Anthropic Knowledge Work Plugins
===================

Anthropic open-sourced 11 Knowledge Work Plugins designed to turn Claude into a role-specific specialist. Built for Claude Cowork with Claude Code compatibility, each plugin bundles skills, connectors, slash commands, and sub-agents for a defined job function.

The 11 plugins cover: productivity, sales, customer-support, product-management, marketing, legal, finance, data, enterprise-search, bio-research, and cowork-plugin-management (the meta-plugin for creating or customizing plugins).

Each plugin connects to specific external tools. The sales plugin integrates with HubSpot, Close, Clay, ZoomInfo, and Fireflies. The finance plugin connects to Snowflake, Databricks, and BigQuery. The data plugin links to Snowflake, Databricks, BigQuery, Definite, Hex, and Amplitude. Enterprise-search provides a single query across Slack, Notion, Guru, Jira, Asana, and Microsoft 365.

The bio-research plugin stands out. It connects to scientific databases: PubMed, bioRxiv, ClinicalTrials.gov, ChEMBL, Open Targets, and Benchling. This targets early-stage life sciences R&D workflows specifically.

The cowork-plugin-management plugin is the key enabler. It lets teams create new plugins or customize existing ones for their organization's tools and workflows. The out-of-the-box plugins are starting points. Customization for company-specific terminology, processes, and tool stacks is the intended path.

Installation for Claude Code:
claude plugin marketplace add anthropics/knowledge-work-plugins
claude plugin install sales@knowledge-work-plugins

For Cowork, installation goes through claude.com/plugins. The plugin architecture bundles four components: skills (behavioral definitions), connectors (SaaS integrations), slash commands (user-facing actions), and sub-agents (delegated tasks).

The open-source approach allows inspection of plugin definitions before deployment. What the source does not document: how connectors authenticate to SaaS tools, whether data accessed through connectors leaves the organization's tenant, and what guardrails exist around write actions. Organizations with compliance requirements should verify these specifics.

Я держу 4 Claude-инструмента в работе. HBR говорит, что у таких brain fry. Я был среди них

Harvard Business Review опубликовал в марте 2026 исследование на 1488 сотрудников - пользователи ИИ получают острый brain fry от oversight’а. Я держу 4 Claude-инструмента и думаю добавить пятый. Был уверен что у меня “архитектура другая”. Перечитал и все таки нет. Три случая где меня ловило, чек лист на 7 пунктов где я падаю, и почему добавление Codex ровно то, что HBR ругает. Я в этих 14%. Разбираю.

When Microsoft 365 Copilot Cowork needs to create an Excel file, it uses LibreOffice - not Excel.😏

The actual process seems to be: Claude agent calls openpyxl (Python library) to generate the file. Then, the headless soffice of LibreOffice is used to validate the output. Finally, the user is shown a file in Excel for the web.

It makes perfect sense, given how Anthropic built Cowork and Microsoft just licensed it from them.
